Z53.29Procedure and treatment not carried out because of patient's decision for other reasons

Billable / specific codeICD-10-CM

Z53.29 is a billable, specific ICD-10-CM code for procedure and treatment not carried out because of patient's decision for other reasons. It is valid for submission on a claim.

Risk adjustment

Z53.29 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
